Yoane Steel stands as a leading force in Kinshasa’s industrial landscape, proudly serving as your trusted manufacturer and supplier of high-strength S1100QL steel sheets and plates. We understand the demanding requirements of modern construction and engineering, and we are dedicated to providing materials that offer unparalleled performance and reliability. Our commitment is to empower local and regional projects with products that meet the highest international standards, ensuring strength and durability are always within reach for our partners across the Congo.
The composition of S1100QL steel is meticulously engineered with elements like carbon, manganese, and chromium, often enhanced with nickel and molybdenum, to achieve its exceptional properties. This carefully balanced formula is then subjected to a rigorous quenching and tempering process. The result is a material boasting an impressive minimum yield strength of 1100 MPa, offering an outstanding strength-to-weight ratio alongside good toughness. This combination makes it incredibly resilient against wear and high-stress conditions.
